devices are used
to determine wind
direction.
Weather Balloon
► Weather
balloons carry
electronic equipment
that can measure
weather conditions
high in the Earth’s
atmosphere.

pressure, relative
humidity, wind speed
and wind direction.
Radar

is used to find
the location,
movement, type and
amount of
precipitation.
Satellite
► Weather
satellites
provide images of
weather systems.
► This is the weather
tool that shows cloud
cover.
► Satellites can track
storms and measure
wind speed, humidity
and temperatures at
different altitudes.
